BMW ALPINA B7 BITURBO

Powertrain

Cutting-edge BMW engine technology and comprehensive development work carried out by ALPINA, means output and torque are raised to a whole new level in the BMW ALPINA B7 Bi-Turbo.

The new 4.4 litre 8-cylinder engine with Bi-Turbo charging, petrol direct injection and Valvetronic delivers an impressive output of 447 kW (608 hp) between 5750 and 6250 rpm, while the maximum torque of 800 Nm is available from 3000 rpm.

The resulting performance figures are spectacular – the new BMW ALPINA B7 Bi-Turbo with all-wheel drive accelerates in just 3.7 seconds from 0 to 100 km/h, reaching a top speed of 330 km/h.

The power output of this high-tech engine unfolds smoothly and with impressive vigor across the entire rpm range. Excellent throttle response and high torque ensure that even at low engine speeds driver inputs are immediately transformed into forward acceleration. In every situation there is a fascinating surge to the car‘s power delivery. In addition to the depth of ALPINA’s engineering expertise a number of significant technical details are responsible for the engine’s power output and performance characteristics – specifically the air intake system, the intercooler / turbocharger configuration and the high-performance cooling system.

The Bi-Turbo charging system comprises two specially developed turbochargers with twin-scroll turbines and large compressor wheels, which are positioned in the V of the 8-cylinder engine. This configuration ensures highly effective use of exhaust gas energy even at low engine speeds resulting in a quick power build-up and more torque at low engine speeds for overall exceptional engine response. All components of the ALPINA air intake system - from the so called raw air intake ducts to air filter housings and clean air intake manifold - have been constructed to maximum effectiveness. Similarly, the high-performance cooling system utilises large volume radiators and optimised piping designed for maximum throughput. An indirect inter-cooler system (air/water/air) facilitates the implementation of short charge-air intake paths – with a main intercooler supplying the two large volume engine-near intercoolers. Together with additional external radiators the system ensures the thermodynamic stability of the V8 Bi-Turbo engine at all times even under the highest loads and ambient air temperatures.

 

 

All-Wheel-Drive

The all-wheel drive of the new BMW ALPINA B7 Bi-Turbo draws on the technical capabilities of the BMW xDrive system, which distributes the drive forces continuously and fully variably between the front and rear axle and ensures maximum traction in all situations on the road.

Linked to the engine control and the suspension control systems, torque distribution regulation in the BMW ALPINA B7 Bi-Turbo is geared towards top performance, providing a high level of driving dynamics and agility while maintaining neutral handling. The DTC mode of the stability control system offers an even more rear-wheel drive biased setting for maximum sportiness.

 

 

Exhaust System

The stainless steel ALPINA sports exhaust system steel provides a powerful sound as well as reduced exhaust gas pressure and decreased weight. The acoustic pattern is sporty and bass-driven and can be adjusted by means of an air flap control – from vibrantly athletic and emotional to reticent for maximum travel comfort. A typical ALPINA feature: the two twin tailpipes of the exhaust system are integrated elegantly and aesthetically into the rear apron.
